Module gates 

Framework-inserted TX/RX gate ops. Each gate is a compiler- inserted graph op that consults a framework primitive (PeerGovernor, BackoffTable, InboundDedup) and either forwards its envelope/trigger downstream or drops + emits a lifecycle event.

TX-side chain (around wire::Send): wire::Send → PeerHealthGateTx → BackoffGateTx → outbound

RX-side chain (around wire::Recv): wire::Recv → DedupGateRx → PeerHealthGateRx → BackoffGateRx → user consumer

Modules

backoff_rx

BackoffGateRx syscall op - gate inserted by the compiler pass bb-compiler/src/insert_backoff_gate_rx.rs in the RX chain. Consults bb_runtime::framework::BackoffTable for the inbound envelope’s source peer and forwards the input value on retry- eligible; drops with a cooldown reason when the peer is still in backoff.

backoff_tx

BackoffGateTx syscall op - gate inserted by the compiler pass bb-compiler/src/insert_backoff_gate_tx.rs between PeerHealthGateTx and wire::Send. Consults bb_runtime::framework::BackoffTable and drops the send if the destination peer is still in cooldown.

dedup_rx

DedupGateRx syscall op - gate inserted by the compiler pass bb-compiler/src/insert_dedup_gate_rx.rs at the head of the RX gate chain. Consults bb_runtime::framework::InboundDedup and drops envelopes whose payload hash has been seen recently.

peer_health_rx

PeerHealthGateRx syscall op - gate inserted by the compiler pass bb-compiler/src/insert_peer_health_gate_rx.rs between every synthesized wire::Recv and its downstream consumers.

peer_health_tx

PeerHealthGateTx syscall op - gate inserted by the compiler pass bb-compiler/src/insert_peer_health_gate_tx.rs upstream of every wire::Send. Consults bb_runtime::framework::PeerGovernor and emits a TriggerValue on Allow; the downstream wire::Send fires only on Allow. On Deny the op returns an OpError whose detail carries a stable label (blocklisted / not_allowlisted / cooldown).
